Synopsis
by Hal Erickson

Sister Mary is a fictional character in a popular British soap opera. When Sister Mary is killed off by the scriptwriters, a mentally unbalanced fan objects. The fan insinuates himself (or herself?) on the set of the program and begins bumping off the other actors. Jennie Linden plays the title character in this predictable thriller, while top-billed George Maharis tries to prevent further carnage. Videotaped in London, Death to Sister Mary debuted in America on May 21, 1974, as part of the late-night anthology ABC Wide World Mystery.
